Open AccessFluid effects in model granular flows
Pore fluid plays a crucial role in many granular flows, especially those in geophysical settings. However, the transition in behaviour between dry flows and fully saturated flows and the underlying physics tha...

The Illgraben Torrent System
The catchment is one of the most active in the European Alps, with between 2 and 7 or similar debris floods occurring every year since the start of systematic observations from 2000 to the present. The u...

Infrasound produced by debris flow: propagation and frequency content evolution
Rapid mass movements such as avalanches, debris flows, and rock fall are periodic or episodic phenomena that occur in alpine regions. Recent studies have shown that debris flows generate characteristic signals...

Runout Prediction of Debris Flows and Similar Mass Movements
All around the world, people meet a challenge to find a balance between the risk of natural hazards and the need for spatial developments. Densely populated hillside regions in humid, subtropical or tropical c...

Measurements of hillslope debris flow impact pressure on obstacles
We present measurements of hillslope debris flow impact pressures on small obstacles. Two impact sensors have been installed in a real-scale experimental site where 50 m3 of water-saturated soil material are rele...

A debris-flow alarm system for the Alpine Illgraben catchment: design and performance
We describe the development, implementation, and first analyses of the performance of a debris-flow warning system for the Illgraben catchment and debris fan area. The Illgraben catchment (9.5 km2), located in th...
